Biogas produced from cattle, pig, buffalo dung and kitchen waste has a by-product called bioslurry which can be used as excellent organic manure. Bioslurry is used to improve soil fertility, soil structure, and crop productivity. However, not many farmers are familiar with the advantages of bioslurry.
Bioslurry is an easily available form of compost compared to traditional compost. It is also attractive to mix with waste compost. The bioslurry can be applied:
- As a foliar fertilizer, being sprayed onto the crops
- In liquid form (diluted) onto the roots
- In dry and composted form (combined with irrigation techniques so that crops have sufficient water).
Cow dung or bioslurry?
Bioslurry can replace cow dung which is used a fertilizer in cultivation. Dung manure and biogas slurry are of two types. Since decomposition in dung manure has not taken place completely, it will take time for the plants to absorb the micronutrients contained in it. Manure is beneficial for long term and biogas slurry for short term.
|Nitrogen||1.5%||1.6% to 1.8%|
|Phosphorus||0.3%||1.1% to 2%|
|Potassium||0.2%||0.8% to 1.2%|
Things to take care of while using Bioslurry
- Solid fertilizers i.e. manure or various types of compost should be given along with bioslurry. Thus plants will get enough nutrients which will enrich the soil that in turn results in quality yield.
- If you are giving only slurry then it should be given continuously. If not given, the plants will become unhealthy.
Uses of Bioslurry :-
- s a plague repellent
- To increase soil fertility
- To improve the soil structure and water retaining capacity
- To prevent soil erosion
- To treat seeds for higher germination, disease resistance, better yields, improved coloration of fruits and vegetables, and tenderness and taste of leafy vegetables
- For concentrated feed for cattle, pig, and fish and the production of earth worms and algae
- As manure for pot grown flowers and vegetables
- To increase the availability of nutrients for soil
- To reduce wastewater and water pollution
- To reduce weed growth and to reduce attractiveness to insects or flies
- To reduce the number of pathogens as it is almost pathogen free.
